ZR-1 newbie oil change question

[RedrockLT5]

Just got my 92 red/red and just love it! Previous owner said oil was changed last fall and with almost no miles on the new oil but think I'll change it just so I know for sure when done last. My question: Need to lift the car a few inches to get oil pan under car so I thought I'd drive it up on my ramps (6 inches of lift), and allow the oil to drain over several hours. WIll this mess up the amount of oil drained and that needs to be replace? I believe it's 8.5 quarts with filter right?

Sorry about the trivial question but I want to do this right.

Thanks for your help

some will tell you it needs to be left to drain over night, but I think that's rubbish. I've let mine drain for a much shorter length of time and always had around to replace ~8 or 9 quarts of oil with the filter.

Every "drain" will or could be different until you develop a procedure and follow it specifically. Your 6" of lift is going to effect yours I'd think for sure. How much? Don't know. Let it drain for a couple hours. Was it full when you "sticked it cold"? Did you stick it cold? If you haven't if the car is on all fours and "cold" with "no starts' stick it and see where you are before you start.

So what would you recommend? I need about an extra 1" of clearance to get pan under. Would like to avoid using jacks as I'm not sure where I can safely put the jack to avoid damage to the car. The 92 "Z" is different than my 90 vert. Also, I know there's been a running debate about the best way to jack a C4 with no consensus. Thought maybe I could drive it up on two stacked boards (would give me 1.5"). Sure seems like the ramps would be easiest and safest for all concerned. Opinion?

90 and 92 frames are the same - jack on the sides at the arrows or front middle on the cross member. I like to have the vehicle level to get a complete drain.

Perfect....I do exactly as you do when changing oil.......the little oil you might miss this time you will get next time and you will definitely leave some oil in the engine when you drain...NO PROBLEM

Let it sit over night (or a couple hours) before you remove the oil filter to make sure the oil filter has drained back. Just add 8-9 quarts of oil. The best time to check oil is one pull of the dipstick after it has sat for several hours. Take the first reading as just removing/replacing the dipstick leaves oil in the dipstick tube which messes up readings after the first.

I use AMSOIL 10W 40 Synthetic LT5/ZR-1 Fluids

I have some small raceramps that I use for this for the same reason. I leave it overnight but you can probably get away with a few hours if you need to turn the car around quicker. As everyone says, it's hard to get all the oil out of the LT5 but the small amount left isn't really a problem.
